Explaining the conditions for the evolution of cooperation in groups of unrelated individuals is an important topic for natural and social scientists [1]}, [2]}, [3]}, [4]}, [5]}. Research on the subject has been extensive and has lead to the identification of several mechanisms contributing to the success of cooperative behaviour: direct and indirect reciprocity, spatial selection, kin selection and multi-level selection, and punishment [4]} among others. A large number of situations in which cooperation is difficult to achieve involve the pursuit of collective action to address problems beyond the individual dimension [7]}. Such problems are frequently studied through variations of the public goods game, where the public goods thrive through the contributions of its participants. While the social optimum is achieved when everyone's contribution is maximal, individuals always have the temptation to withhold their contributions, free-riding on the efforts of others [8]}.
